' ANTISLIPPING nnvrcn ron snons.

T 0 all whom it may concern:

Be it known that I, HAROLD E. CLARKE, a citizen of the United States, and a resident of Somerville, in the county of Middlesex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Antislipping Devices for Shoes, of which the following is a specification.

My invention relates to a type of device which is used principally for outdoor athletic sports, such as base-ball,but which may be with some slight modification used as an ice-creeper.

It has been the special object of my invention to provide a device which shall be readily attachable and detachable without injury to the shoe of the wearer and which, when attached, shall not be subject to accidental displacement.

It has been my further object to make a device which may be easily and cheaply manufactured.

My invention may be best understood by reference to the accompanying drawing in which Figure 1 is a top view of my device with the sole of a shoe to which the same may be attached indicated by dotted lines. Fig. 2 is a cross-section on line 2-2 of Fig. 1. Fig. 3 is a cross-section on line 33 of Fig. 1.

Referring now more specifically to the drawing in which like reference characters indicate like parts, A is a plate preferably made of rigid, thin steel and provided with upturned ears B which are formed to em brace the outer edge of the sole of a shoe, having bent-over ends I) for this purpose. Projecting downwardly from plate A are three spikes 0 formed and arranged in the well-known manner of base-ball spikes, they being integral with plate A, which plate is preferably cut away in its central part so as to make the device lighter.

Plate A has two depressions a which are provided with threaded holes through which may be inserted screws D, the upper ends of which are cupped or hollowed so as to form a sharp annular edge (Z for contacting with the sole of a shoe, and best indicated in Fig. 3. Because of the depressions a in the plate A the screws D will have a bearing in the plate A near their central parts while they are in contact with the shoe, thus insuring strength and certainty of engagement of the Specification of Letters Patent.

screws D with the plate A. The thread upon the screws D is preferably not continued as far as their cupped extremities so that they must be entered in the threaded holes in plate A from the top and screwed downwardly therein. Hence it is impossible for the screws D to accidentally loosen a drop out.

To fasten the device to a shoe the screws D are first positioned so that their tops are substantially level with the top of plate A and the device is slipped on to the sole of the shoe until the ears B are in firm engagement with the edges thereof. The screws D are then set up tightly against the sole so as to cause the bent-over portion 6 of ears B to bear firmly upon the top of the sole. The annular rims at the top of the screws D will thus come into firm engagement with the bottom of the sole of the shoe and will, together with the bent-over portion 1) of the ears B, hold the device firmly upon the shoe.

It is to be noticed that the screws D are placed on either side of the plate A in close proximity to the ears 13. Thus the bent-over parts Z) of the ears B have the effect of holding the sole of the shoe and preventing its being bent upwardly by the pressure of screws D as would be the case were the screws D nearer the center of the sole. obvious that were the sole of the shoe allowed to be pushed upward by pressure of the screws the screws would not get a firm grip upon the sole and serious discomfort would be caused to the foot of the wearer.

It is to be understood that I do not limit my invention to the precise arrangement of parts as shown in the drawing as the arrangement and shape of spikes and the placement of screws may be varied.

Having thus fully described my invention what I claim is 1. In a device of the character specified a plate, spikes 011 the said plate, ears on said plate, arranged to embrace the edge of the sole of a shoe, and screws mounted in said plate and arranged to be brought into contact with the bottom of the sole of said shoe and thereby draw said ears downward into firm engagement with the edge of the sole thereof.
